Controllable nonlinear propagation of partiallyincoherent Airy beams

The self-accelerating beams such as the Airy beam show great potentials in many applications including optical manipulation, imaging and communication. However, their superior features during linear propagation could be easily corrupted by nonlinearity or spatial incoherence individually. Here we investigate how interaction of nonlinear affect quality beam, find that two destroying factors can fact balance each other. Our results influence coherence on partially incoherent (PIABs) formulated exponential functions have opposite signs. With appropriate length, PIABs not only resist corruption profile caused self-focusing nonlinearity, but also exhibits less anomalous diffraction self-defocusing nonlinearity. work provides deep insight into to maintain exploiting between may bring about new possibilities for optimizing structured field developing related communication, manipulations.
